UN Warns Of 'Major Shock' As Africa Locust Outbreak Spreads Associated Press JOHANNESBURG - Uganda scrambled to respond to the arrival of the biggest locust outbreak that parts of East Africa have seen in decades, while the United Nations warned Monday that "we simply cannot afford another major shock" to an already vulnerable region. An emergency government meeting hours after the locusts were spotted inside Uganda on Sunday decided to deploy military forces to help with ground-based pesticide spraying, while two planes for aerial spraying will arrive as soon as possible, a statement said. Aerial spraying is considered the only effective control. .
